Did you download WWF from Snap? When you open Words, it will show a pop-up that your phone needs Google services, but if you tap the screen outside of the pop-up message, it will go away, and you can play Words.

I get a message similar to that using the classic Words With Friends but I am able to close the message. New Words With Friends works smoother and faster for me but the instant messaging part does not work. I downloaded WWF, Netflix, etc. using APK Downloader ( http://apps.evozi.com/apk-downloader/ ) You find the App you want on Google Play Store's website, copy the URL, and paste it in the box on the APK Downloader site and click generate download link. From there you can download the APK files for whatever app you find on Google Play and install it. I do it all from my BlackBerry, a computer isn't required.

I'm having the same problem. I updated my version of Words with Friends using the Amazon app store, and now when I sign on, I get a pop-up screen that says "Welcome Back! Zynga has updated our terms of service and privacy policy. ... By continuing to play, you agree to these updates." But I can't close this screen or continue to play.
